Kylo apparently took out the other students by collapsing Luke's Mojo Dojo on their heads. And to say that Kylo has as much training as Luke means remarkably little considering how much training Luke had.

I said he isn't well trained. And I say that because he was incompletely trained by Luke and Luke himself is mostly self-taught and because
1. His lightsaber may look intimidating but it only has those crossbars because he screwed up when making it and nearly killed himself. .
2. He muffed his attempt at a mind probe and ended up just dumping his own memories into her mind and creating a permanent but accidental mind link.
3. He was directed so that he'd swing his saber like it weighs 20 pounds.
4. He is profoundly undisciplined.
Powerful? Yes. Well-trained? No.

She hasn't lost a fight to date because she was so drastically overpowered by Snoke that she couldn't even put up a fight. The thing is, Kylo Ren may be the main villain but he had a huge stack of handicaps when he fought Rye, and Ren isn't at all well trained himself. Even so he could have easily killed Rey if he had in fact been fighting to kill her.

That boat sailed in the first movie when all it took was an afternoon with a bucket on his head for Luke to get superpowers. Star Wars could have been written as "Luke spent years meditating and training in his apprenticeship and then he could lift a rock or block blaster shots" but that's not the way Lucas went with it.

Random Jedi? Rey is 20 give or take. There were no "random Jedi" 20 years before her time. I think it's funny that so many people object to "mitochrondria" while at the same time strongly wanting Force ability to be a genetic trait. But genetics are complicated. I mean there's a genetic element to intelligence but also plenty of examples of geniuses whose parents were nothing special.

Most powerful characters...but just however powerful is "Most powerful"? Are they impervious to tank shells and artillery? If they aren't, then deploying them on the field of open battle is probably not the optimal way to deploy them. They are valuable scarce assets. Risking them on jobs that can be done by a few mass produced tanks or planes is a waste. By and large superheroes should usually be used on the kind of job that historically was carried out by commandos and covert operatives or to stop hostile superheroes doing those kind of jobs.

Hey there Cthulhu, down there in your sunken city
You're a billion light years distant and the stars look very pretty
From R'lyeh
So close and yet so far away
Iä, Ië
Cthulhu Fhtagn, or is that k-THOO-loo fuh-TINE?
I can never quite remember, 'cause I'm not in my right mind
Since I met you
No one corrupts the way you do
You know it's true
Oh, it's what you'll do to me
Oh, and all humanity
Oh, you'll rise up from the sea
Oh, kill everyone slowly
Except the ones like me
Hey there Cthulhu, I've been studying your gospel
The Necronomicon, it gives me nightmares something awful
Where I see
The death of all reality
It fills me with glee
So when the stars are right, you'll come and do your worst
But that's okay because I know you'll eat the cultists like me first
When you get here
I know that day is DRAWING near
I have no fear
Oh, it's what you'll do to me
Oh, and all humanity
Oh, you'll right up from the sea
Oh, kill everyone slowly
A billion light years seems so far
BELOW the sea, beyond the stars
Of these humans' putrid souls you'll drink your fill
The fools will all make fun of me
But I'll just laugh maniacally
'Cause no one's ever suffered like they will
Cthulhu, I can promise you
That by the time this cult gets through
The world will never ever be the same
Praise your dark name!
Phn'glui mglw'nafh Cthulhu R'lyeh wagh'nagl fhtagn
Boy, that's really quite a mouthful, can't quite cram it in my noggin
Not today
I try to say it anyway
I feel my soul begin to fray
Still I await that frabjous day
Cthulhu calay!
Oh, it's what you'll do to me
Oh, and all humanity
Oh, you'll rise up from the sea
Oh, kill everyone but me
Everyone but me

I love you all but sometimes, you boys are way too much
Been gone too long and this place could use a female touch
Oh, you've been waiting for me?
